PROBLEM TO BE SOLVED: To facilitate mounting of a pull for a fire door. SOLUTION: A pull main body 5 for the fire door is set up by forming a finger hooking hole in a metal plate 2, and mounting a metallic recessed member 4 on a rear surface of the metal plate in the vicinity of the finger hooking hole 3. Then an engaging piece 6 is arranged on a rear surface of the pull main body 5 for the fire door, on one side of the recessed member 4, for engaging with a mounting hole 11 formed in the fire door. Further a plate spring 8 which has an elastically deformable engaging projection 7 engageable with the mounting hole 11 formed in the fire door on the other side of the recessed member, is secured to the recessed member 4.
